IMPROVEMENT IN THILLS FOR VEHICLES.

Specification forming part of Letters Patent No. 144,558, dated November11, 1873; application tiled October 6, 1873. i

To all whom it may concern:

Beit known that I, ANDREW MUHLEISEN, of Ottawa, in the county of Putnamand State of Ohio, have invented certain new and useful Improvements inThills or Shafts for Car riages, Wagons, 8vo., ofwhich the following isa speciiication:

This invention has for its Object the production of shafts or thills forvehicles, the form and arrangement imparted to such being that when thesame are connected with the front axle of a vehicle the position of thedraft-animal will be such as not to be compelled to travel upon theridge created between the beaten tracks by the continued passage ofdouble teams, but said animal will be permitted to travel in one of thebeaten tracks without necessitating the wheels of the vehicle to leavethe track made by the wheels of the double teams. My invention consistsin forming one thill together with the cross-bar in a single piece, theend of the cross-bar being connected with the other thill at a point soas to leave a projecting rear end, while a similar rear end or arm isunited with the shaft formed with the cross-bar, the object of suchbeing to admit of the shaft-irons being bolted thereon for the purposeof connecting the shafts with the axle or thill-coupling of the carriageor wagon. My invention further consists in providing the thills with a1aterallyproj ecting arm having suitable means for connecting it withthe axle, in such a manner as to strengthen the shafts and counteractany lateral strain exerted upon the shafts, and further, to secure anequal draft at both ends of the front axle, thus causing the carriage orwagon to travel in a straight line with respect to the draft animal.

In the drawings, Figure l represents a top or plan view of my thills.Fig. 2 is a detached view of the shaft-irons.

Referring to the drawing, A represents the thill,.and B the cross-barfor connecting with the opposite thill or shaft C. The shaft A andcross-bar B are bent or formed of a single piece from suitably-seasonedwood, by steaming and bending the same in the usual manner of bendingwood. The shaft or thill C is of the usual construction and is connectedI prefer to construct the lateral arm D in a single piece with theshaft-iron E, as shown in Fig. 2, which shaft-iron possesses anextension, a, and arm b, for strengthening the point of union betweenthe thill O and cross-bar, and the arm b of which passes along beneaththe thill O and serves as a means of connect ing the same with the axle.A

The point of union between the thill A and arm F is strengthened by theshaft-iron G, which possesses two branching arms, c d, corresponding tothe shape of the thill A and cross-bar B, and an arm, c, which passes beneath the arm F, and serves as a means of connecting the thill A withthe axle.

By the construction above described I produce thills for vehicles whichpermit the draft animal to travel in one of the beaten tracks made bythe continued passage of double teams, and which also permits the wheelsof the carriage or wagon to pass in the track made by the wheels of thedouble team. V

All lateral strain on the front axle, which would follow to a slightdegree the construction and arrangement of my shafts, is

counteracted by the laterallyprojectmg arm D attached to the axle of thevehicle, and au equal draft of both ends of the front axle is secured,thus causing the vehicle to travel in a straight line with respect tothe draft animal.

The curved cross-bar B may be furnished with the usual devices forattaching the whifetree, which whiffletree I prefer to make of a formcorresponding to that of the curved cross-bar.

I claim as my invention- 1. The side thill A, having the curvedcrossbau' B and an arm, F, in combination with In testimony tht I claimthe foregoing I the side thill C, adapted to receive shaft-ironsr havehereunto set my hand this 22d day of E, substantially as shown anddescribed, for September, 1873. the purpose specified.
